Citrix: Configuring GSLB for XenMobile
Customers have many requirements. As I usually deal with large customers, a disaster recovery solution is always one of them.
With XenMobile 10.x, things have gotten a lot easier: clustering is a piece of cake, and to direct traffic to the right data center we have NetScalers and GSLB (Global Server Load Balancing) at our disposal. This post is about configuring GSLB on NetScalers for XenMobile.
Now, before I continue, I do want to clarify that I’ll be discussing a configuration for disaster recovery (DR), NOT High Availability (HA). Those are two different solutions for two different problems. It’s one of my pet peeves (I have a large collection of peeves) how this gets confused all the time and often the same solution is used to cover both (hint: you shouldn’t). That’s a topic for a whole other blog article. This solution isn’t the only solution, nor is it necessarily the best one. However, it’s fairly simple and I know it works as it has been deployed in production environments.
Some assumptions before I start:
- I am using two data centers: PROD (where my production servers are), and DR (where DR servers are located).
- Both data centers are connected using a reliable link (just to simplify the design. If the link is not reliable then you have a some additional GSLB configuration to do). However, latency between both data centers exceeds 10ms and thus I really need to put in an active/passive solution.
- We are using XenMobile version 10.3.6, although this will work with any XenMobile 10.x released at the time of writing.
- There is a NetScaler in each data center, and each data center has it’s own internet connection with public IP addresses.
- I am using MDM.CCSLABS.BIZ as my enrollment and MDM server address and MAM.CCSLABS.BIZ as the MAM or NetScaler Gateway address.
- I configured both NetScalers using the XenMobile wizard.
